Seasons In Nepal: Base Camp Trek Adventures

If you are a travel enthusiast looking forward to scaling a trip to the Himalayas, it is essential to understand the seasons and the good time here. Nepal is a mesmerizing nation with so much to offer, and trying to squeeze the best out of the trip is a must for everyone. Spring in Nepal is a beautiful and colorful season that spans from March to May.

Here, the only way to make it a once-in-a-lifetime experience is to understand the preferable trekking season and plan the trip accordingly. Casually speaking, there is no such thing as the right time to go for an adventure or thrill, nor is there an appropriate itinerary for the whole trek, as it all depends on one’s preference and expectations.

However, the best seasons to start your travel in Nepal are during Spring and when Autumn starts. Yet again, all these conditions are also highly dependent on the location you are traveling to, the maximum altitude, crowd preference, and the tolerance to the weather conditions.

When you hit the base camp trek, it should be known that the weather in that region gets harsh during the cold, often making it impossible to scale. The very same reason also keeps the trails closed for travelers.
